Unformatted text preview: Class 6 Notes • Global Temperature o Elevation= thinner atmosphere in troposphere means less greenhouse Snow accumulation on mountain peaks o Insolation= daily and seasonal variations o Latitude= daily and seasonal variations o Surface type= albedo (extent surface reflects sun light) of surface as well as surface moisture Cities landscapes heat up more quickly b/c less water to evaporate and cool it o Coastal vs interior location= temp range is lower at coasts b/c water heats and cools more slowly o Layers in atmosphere= Troposphere – temps decreases with elevation Heats again as you go up because of intense solar radiation o Auroras= only visible >60N/S Occur when high energy particles from Sun become trapped by Earth’s magnetic field Magnetic field bend down closest to earth at Poles • Daily Temperature Variations o Insolation and net radiation undergo daily cycles of change because rotation o Variations in net radiation are responsible for particular patterns of rising and falling...
